Cathedral of Justo Gallego Martínez

The Cathedral of Justo, sometimes also called a "cathedral of faith", is a religious building of grand proportions, much a like a cathedral, located in Mejorada del Campo on the outskirts of Madrid, Spain. It is named after Justo Gallego Martínez, who initiated the building and who worked on it almost singlehandedly until his death at the age of 96. The building was donated to the Catholic organisation Mensajeros de la Paz to complete its construction after his death. Although the building is called a "cathedral", it has no official recognition from the Catholic Church in the Diocese of Alcalá de Henares.
